To all 'whom tt vmay concern:

Be it known that we, Louis BERNARD GAST and JACOB GAST, Jr., citizens of the United States, residing Akron, in the county of Summit and State of Ohio, -have invented new and useful Improvements in Vehi4 cle-Rims, of which the following'is a specification.

This invention relates to vehicle wheel rims adapted to seat pneumatic, solid or cushion tires of elastic -material, more particularly pneumatic tires of the doubletubo typo, having contractible, inextensible or semiinextensihle bands or edges, and the object thereof is to so construct the rim as to enable the tire to be readily applied thereto, and to be securely locked in position thereon and easily removed when desired.

A further object of this invention is to provide, a new and improved rim for a wheel upon which the tire is to be mounted, provided with means for suitably seating a tire-retaining device thereon, andto further provide a novel tire-retaining device capable of cooperation with said rim.

The invention further aims to construct thetireretaining means so that .when in position it will be locked against circumferential motion and also held from side wisc displacement.

With the foregoing and other objects in view, the invention conssts'ofthe novel construction, combination and arrangement of parts constituting the invention to be hereinafter referred to and illustrated in the accompanying drawings which form a part of this specification in wh? "l1 is shown the preferred embodiment of the invention, but it is to be understood that changes, va@ riations and modifications can be resorted to which come within the scope ofthe claims hereunto appended.

In the drawings, in which similar reference numerals indicate like parts in the different figures: Figure l is a crosssection of a vehicle wheel. rim constructed in4 ac cordance with this invention, also showing in cross-section the detachable retaining means for securing the tire, said retaining means arranged in position to re'- ceive that form of tire knownas the clencher type; Fig. 2 is a side elevation ofa rim shown in Fig...l Fig. 3 is a view similar to Fig. 2 of the detachable tireretain ing means; and, Fig. 4 is a side elevation of a vehicle wheel rim embodying my invention.

Referring to the drawings, 1 denotes a flat rim having one side formed with an endless-offset 2 of a cosssec- I tional configuration to suitably/.receive a tircretaining ldevice and form a seat therefor..

In the construction shown, the offset 2 is on the level with or depends below the upper face of the rim. The opposite side ofthe rim has an upwardly-extending endless inclined curvilinear flange 3, constituting a tireretaining means for one side of a tire. The offset 2 is provided with an outer upwardlywxtending flange 4. At regolari y-recurring intervals in this flange 4 are cut a se ries of notches 5 which extend in depth `to the bottom of the seat in the offset 2. The tii e1'etaining device whichI is arranged to be used for retaining a tire on the side opposite to that retained by the curvilinear flange 3, con sists of an uninterrupted annular member 6 having an upper portion thereof, designated in the drawings by lthe reference numeral 7, shaped to engage the base or shoe portion of a tire, and to correspond in contour to the shape of the flange 3. The diameter' of the interior of the main portion of this member 6 is slightly greater than the diameter of the rim 1, so that it may fit thereover and seat thereon. Extending inwardly from the inner face of the main portion of the member 6 are a scries of regularly-recurring lugs 8, 8, of a size to nicely pass through the notches 5 in the flange/4.

In order to prevent any accidental circumferential motion `of the member 6 in its seat, there is cut through the bottom of the offset 2 a. slotf9 inwhich is placed ar key'10. This key 10 is of such a size that when raised so that its under face is flush with the under face of the offset 2, its upper portion will' project upwardly into the groove or seat in the offset 2 and be substantially flush with the outer face of the rim l. In order to normally maintain this key in the position just described, we employ two springs, designated in the drawings by the reference numerals l1, which are fastened to the under face of the offset 2 and have the normal tendency to raise the key 10 into such a position as to project into the seat in the offset 2. The under face ofthe key 10 bears a hook or eye 12, the shank-end of which passes through suitable slots inthe springs 11 and the function of which will be described later. The key 10 is placed in the offset 2 at a point directly opposite the point in the flange 4 where one of the notches 5 would normally occur, but the notch at this point is, omitted, for a pun pose which will later appear. In placing the member 6 in'its seat in the offset'2, the member A6 is so placed swung sidewise into position, which is permitted by the fact that the lugs B will register with the corresponding notches 5. The key 10 being now flush with the bottom' of the seat in the offsetrl, no obstruction is offered to a partial rotation of the member 6 in its seat, and it is then rotatedv sufficiently to bring one of the spaces existing between the lugs 8 and 13 in the member 6 over the point where the key 10 is, which will then be forced upward into this space by reason of the influence of the springs 1i. The position of the key ,l1 is then between one ofthe lugs 8 and the lug I3, which securely locks thc uicinbcr t3 l'i'oni t-ircunilcrcntial motion in its seat.

ln order to withdraw the incniber (l7 the hook or eye l2 is grasped b v a suitable tool and the key l() drawn out ol' th(l scat in the ol'l'set 2 sutlicicntly to permit a reverse rotation oi the. nicinber t3 until it has reached a. point where the lugs S will register with tlie notches 5, and it.
